CROSS-REFERENCE TO RELATED APPLICATION(S)

This application is a continuation application of prior application Ser. No. 14/472,944, filed on Aug. 29, 2014, which claimed the benefit under 35 U.S.C. § 119(a) of a Korean patent application filed on Sep. 2, 2013 in the Korean Intellectual Property Office and assigned Serial number 10-2013-0105093, the entire disclosure of which is hereby incorporated by reference.

TECHNICAL FIELD

The present disclosure relates to a method and an apparatus for configuring a multi-window based on an input and simultaneously providing various applications in an electronic device.

BACKGROUND

An electronic device may be configured to provide various applications. For example, the various applications may include an application for exchanging a message through a network, an application for obtaining an image through a camera, an application for providing voice communication, an application for reproducing a video, an application for receiving a broadcasting signal and providing a video or audio program, and the like.

Further, the electronic device may be implemented in various types. Various types of electronic devices include a stationary electronic device such as a TeleVision (TV) having a large display, a portable electronic device such as a smart phone having a portable size, a wearable electronic device such as a watch, glasses, clothes, or a belt which can be worn on a user's body, and the like.

The electronic devices include an electronic device which simultaneously provides a plurality of applications through a plurality of windows (for example, a multi-window) according to a user's request for simultaneous reception of various applications.

Recently, electronic devices may configure a plurality of applications in a multi-window type, so as to provide convenience to users. However, a configuration of the multi-window type is fixed to a predetermined form. Particularly, a fixed multi-window for executing a plurality of applications calls and uses a multi-window bar for user convenience. The multi-window bar is disposed in a predetermined area of a display and has a button unit for calling the multi-window. As a result, the multi-window implementing a plurality of applications having the multi-window bar and the button makes the configuration for various execution screens complex. For example, a layout of a window is configured while an application which a user desires to execute is selected from various applications and is executed by a tap action or a drag & drop action. The window may be switched to a pop-up window through an additional menu of an application being executed on an entire screen or another function is performed on a pop-up window by an additional call related to the application while the application is executed. Accordingly, such a method has a limitation and deteriorates the appearance.

The above information is presented as background information only to assist with an understanding of the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the present disclosure.

FIG. 1 is a block diagram illustrating a configuration of an electronic device according to various embodiments of the present disclosure.

Referring to FIG. 1, the electronic device may include a wireless communication unit 110, a storage unit 120, a touch screen 130, a controller 140, and other similar and/or suitable components.

The wireless communication unit 110 may perform communication of the electronic device. The wireless communication unit 110 forms a communication channel with a supportable mobile communication network to perform communication, such as voice communication, video communication, data communication and the like. The wireless communication unit 110 may include a radio frequency transmitter for up-converting and amplifying a frequency of a transmitted signal and a radio frequency receiver for low noise-amplifying and down-converting a frequency of a received signal. Further, the wireless communication unit 110 may include a mobile communication module (for example, a 3-generation mobile communication module, a 3.5-generation mobile communication module, a 4-generation mobile communication module or the like). In addition, the wireless communication unit 110 may include a short-range communication module for supporting a short-range communication technology (for example, Bluetooth, Bluetooth Low Energy (BLE), Near Field Communication (NFC), or the like).

The storage unit 120 may store a program and data required for operations of the electronic device and may be divided into a program area and a data area. The program area may store a program controlling general operations of the electronic device, an Operating System (OS) and an application program booting the electronic device and the like. The data area is an area storing data generated according to the use of the electronic device and may store, for example, an image, a dynamic image and the like.

The touch screen 130 is an input/output means for simultaneously performing an input function and a display function, and may include a touch sensor 131 and a display unit 132. Further, when a touch input of an input tool (for example, a finger of the user or an electronic pen) is made by the touch sensor 131 while a particular screen is displayed through the touch unit 132, the touch screen 130 may transmit an input signal according to the touch input to the controller 140. Then, the controller 140 may distinguish touch inputs and control an operation according to the touch input.

According to an embodiment, the touch sensor 131 may detect touch inputs (for example, long press, tap, drag, sweep, flick, multi-touch and the like) of the user of contacting a surface of the touch screen 130. When the touch sensor 131 senses the touch input of the user from the surface of the touch screen 130, the touch sensor 131 may detect a coordinate where the touch input is generated and transmit the detected coordinate to the controller 140. The controller 140 may perform a function corresponding to an area where the touch input is generated, by a signal transmitted from the touch sensor 131. The touch sensor 133 may be configured to convert a change in a pressure applied to a specific portion of the display unit 132 or a change in an electrostatic capacity generated at a specific portion of the display unit 132 into an electric input signal. The touch sensor 131 may be configured to detect a touch pressure according to an applied touch method as well as a touched position and a touched area.

According to any embodiment, the touch sensor 131 may distinguish and detect types of input tools (for example, a user's finger and an electronic pen) performing an input on a window screen (for example, a first window or a multi-window). For example, a touch input by the finger may be identified through recognition of a change in current at a touched position, and an input by the electronic pen (for example, a touch input, a hovering input, or the like) may be identified through detection of an electromagnetic field formed by an electromagnetic induction phenomenon. Further, when a touch input by the electronic pen is generated in a state where a button formed in the electronic pen is pressed, the touch input is distinguished from a touch input through a general electronic pen.

The display unit 132 may display various screens according to the use of the electronic device. For example, a menu, input data, and various pieces of information are visually provided to the user. In any example, the display unit 132 may include a Liquid Crystal Display (LCD), an Organic Light Emitting Diode (OLED), or any other similar and/or suitable display device.

According to an embodiment, the display unit 132 may display a home screen or an application selected by the user on a window screen (for example, a first window or a multi-window). Further, the display unit 132 may display the second window corresponding to a touch input (for example, a finger input by the user or a touch input by the electronic pen) generated by the user in the first window. For example, the second window may be displayed in a pop-up window type or a split window type. For example, the second window may display an application list (for example, an application configured by the user, an application which can be used in a multi-window and the like). The display unit 132 may display (or provide) an application selected by the user from the application list in the second window.

The controller 140 may control operations of the electronic device and a signal flow between internal components of the electronic device (for example, the wireless communication unit 110, the storage unit 120, and the touch screen 130), perform a function of processing data, and control power supplied to the components from a battery.

According to an embodiment, the controller 140 may detect execution of an application according to an input of the user (for example, touch input) and control to display the application in the first window.

According to an embodiment, the controller 140 may change an input mode to a window generation mode. For example, the controller 140 may obtain an input (for example, user input) for executing the window generation mode through the touch sensor 131. When the controller 140 obtains an input of selecting a menu button, the controller 140 may control to display a menu. When the controller 140 detects an input of selecting a window generation mode menu from the displayed menu, the controller 140 may change the input mode to the window generation mode. For example, when the controller 140 obtains the input of selecting the menu button in the window screen (for example, the first window or the multi-window), the controller 140 may control to display the menu. When the controller 140 obtains the input of selecting the window generation mode menu from the display menu, the controller 140 may control to change the input mode for the window generation mode. The controller 140 may change the input mode to the window generation mode according to whether the button 21 of the electronic pen 20 is pressed or whether a generation mode switching menu is selected. Alternatively, when a designated gesture input (for example, an input of drawing a coil) is obtained or an input of drawing a predetermined waveform (for example, a zigzag) is obtained, the controller 140 may change the input mode to the window generation mode. Alternatively, when an input repeatedly moving within a predetermined area is obtained, the electronic device may change the input mode to the window generation mode.

Further, the controller 140 may detect an input (hereinafter, referred to as a “generation request input” for convenience in the description) of the user for generating the second window in a state where the first window is displayed. According to an embodiment, the controller 140 may determine an input generated in a state where the input mode is changed to the window generation mode as the generation request input. For example, when an electronic pen input is obtained in the first window (for example, on the first window) or a neighboring area of the first window (for example, under, over, or around the first window) in a state where the button of the electronic pen is pressed (for example, in the window generation mode), the controller 140 may determine the electronic pen input as the generation request input. In another example, the controller 140 may determine a touch input obtained by the provided User Interface (UI) as the generation request input in a state where the input mode is changed to the window generation mode through the menu button.

In any embodiment, the controller 140 may determine an input obtained on the first window after the input mode is changed to the window generation mode through the menu as the generation request input. For example, the controller may obtain an input of selecting a menu for switching the input mode to the window generation mode and determine an input generated after the switching to the window generation mode as the generation request input.

The controller 140 may recognize a position (or area) corresponding to the generation request input and may control to display the second window based on the corresponding position (or area). According to an embodiment, the controller 140 may obtain an input of drawing a closed curve or an open curve through the touch screen 130 in the window generation mode. The controller 140 may generate and display the second window (for example, pop-up type) inscribed or circumscribed in an area corresponding to the input. Alternatively, the controller 140 may generate and display the second window matching an area corresponding to the closed curve.

According to an embodiment, the controller 140 may detect an input made in the form of line (for example, a curve) of one or more strokes in the window generation mode. The controller 140 may generate and display the second window of an area corresponding to the input (an area corresponding to a rectangle having an upper left coordinate and a lower right coordinate of the line as vertexes facing each other).

According to an embodiment, the controller 140 may obtain an input of crossing at least a part (for example, a part or entirety of the first window) of the touch screen 130 (for example, in a horizontal, vertical, or diagonal direction) in the window generation mode. The controller 140 may generate and display the second window based on the input (for example, generation request input). For example, the controller 140 may split an area corresponding to the first window into a first area and a second area (for example, a horizontal division) based on the input of crossing the first window obtained in the window generation mode, and display the first window in the first area and the second window in the second area. According to an embodiment, the controller 140 may change an application being executed in the first window to be suitable for a size of the first area and display the changed application.

According to an embodiment, when the size of the area corresponding to the input is smaller than a predetermined size (for example, a minimum size which the second window can have (for example, a size larger than ⅕ of the entire screen)), the controller 140 may generate and display the second window having a predetermined size including the area corresponding to the input (for example, the minimum size which the second window can have (for example, a size corresponding to ⅖ of the entire screen)). In any embodiment, when the size of the area corresponding to the input is larger than a predetermined size (for example, a size larger than ⅘ of the entire screen), the controller 140 may generate and display the second window in a predetermined size included in the area corresponding to the input (for example, a maximum size which the second window can have (for example, a size corresponding to ⅗ of the entire screen)).

The controller 140 may display (or provide) an application list related to the second window. For example, the controller 140 may provide an application list which can be executed in the second window. According to an embodiment, the controller 140 may control to display an application list related to the second window in the second window. In the application list related to the second window, an application configured by the user and an application which can be used in the second application may be variously indicated by an icon, a text, a list or the like.

When an input of selecting one application from the application list is obtained, the controller 140 may provide the selected application (for example, second application) to the second window.

The electronic device may have a more or fewer components than those illustrated in FIG. 1. For example, the electronic device according to various embodiments of the present disclosure may include various sensors (for example, an infrared sensor, an illuminance sensor, an image sensor, a proximity sensor and the like) and a broadcast reception module which receives a broadcast signal from an external broadcast management server through a broadcast channel (for example, a satellite broadcast channel, a terrestrial broadcast channel, or the like).

FIGS. 2A and 2B illustrate examples of changing an input mode to a window generation mode according to various embodiments of the present disclosure.

Referring to FIG. 2A, the controller 140 may control to change an input to a window generation mode based on an input. For example, the controller may obtain an input for selecting a menu button 34 of the electronic device, a key button (not shown) of the electronic device, or a menu button (not shown) provided to a first window 201. Based on the input, the controller 140 may generate a menu 30 on the first window 201. The user may select a draw window 32 in the generated menu 30 to generate a window. When the controller 140 detects a touch input of the user input into the draw window 32, the controller 140 may change the input mode to the window generation mode. When the input mode is changed to the window generation mode, the controller 140 may determine the touch input of the user (for example, input by a finger of the user or an electronic pen) as a touch input for generating the window and then operate.

Referring to FIG. 2B, the controller 140 may change the input mode to the window generation mode based on an input of an electronic pen 20. For example, the controller 140 may obtain an input of the electronic pen 20 of touching or hovering on the window (for example, first window or second window). Alternatively, the controller 140 may obtain an input of the electronic pen 20 of controlling a button 21 attached to the electronic pen 20. Alternatively, the controller 140 may obtain a combination of inputs of the electronic pen 20. Alternatively, the controller 140 may generate a menu 36 on the first window 201 based on the input of the electronic pen 20. When the controller 140 detects a user input of selecting the draw window 38, the controller 140 may change the input mode to the window generation mode. When the input mode is changed to the window generation mode, the controller 140 may determine the input (for example, touch input by the user (for example, input by the finger of the user or the electronic pen) as an input for generating the window and then operate.

FIGS. 3A, 3B, 3C, and 3D illustrate examples of displaying a second window according to various embodiments of the present disclosure.

Referring to FIGS. 3A, 3B, 3C, and 3D, in a state in which the input mode is changed to the window generation mode, the controller 140 may detect a touch input of the user in the form of one or more strokes of lines (for example, a curve) on a window screen (for example, first window, multi-window or the like). According to an embodiment, when the input is made in the form of one or more strokes of lines, the controller 140 may generate and display the second window in an area corresponding to a rectangle having two vertexes facing each other in an upper left coordinate and a lower right coordinate of the corresponding line. In any example, the controller 140 may generate the second window based on coordinates of the input lines of one or more strokes. For example, the controller 140 may obtain coordinates of one or more strokes of lines. A length of the line with respect to an x-axis or a y-axis can be calculated using a smallest value and a largest value of coordinates of the x-axis and the y-axis. For example, in a coordinate system indicated by (x, y), the controller 140 may obtain coordinates (2, 6), (3, 7), (4, 7), and (5, 6) of the line. The controller 140 may obtain a length 3 of the line with respect to the x-axis by using a smallest value 2 and a largest value 5 of the x coordinates. Further, the controller 140 may obtain a length 1 of the line with respect to the y-axis by using a smallest value 6 and a largest value 7 of the y coordinates. The controller 140 may generate the second window based on the obtained length of the line with respect to the x-axis or the y-axis. Additionally or alternatively, when the length of the line with respect to the x-axis or the y-axis is smaller than a specified value, the controller 140 may generate the second window by using the specified value.

According to an embodiment, the controller 140 may generate the second window based on coordinates of the input line of one or more strokes corresponding to a horizontal line (e.g., there is no change in a coordinate of the y-axis (for example, an amount of the change in the coordinate of the y-axis=0)) or a vertical line (e.g., there is no change in a coordinate of the x-axis (for example, an amount of the change in the coordinate of the x-axis=0)). For example, the controller 140 may determine a size of the second window (for example, a height) based on the length of the input line of the y-axis when the line corresponds to the vertical line (for example, the amount of the change in the coordinate of the x-axis=0) and determine a size (for example, a width) of the second window based on a predetermined size (for example, a rectangle according to an aspect ratio, a square corresponding to the input line length or the like). Alternatively, the controller 140 may determine a size of the second window (for example, a width) based on the length of the input line of the x-axis when the line corresponds to the horizontal line (for example, the amount of the change in the coordinate of the y-axis=0) and determine a size (for example, a height) of the second window based on a predetermined size (for example, a rectangle according to an aspect ratio, a square corresponding to the input line length or the like).

Referring to FIG. 3A, according to an embodiment, the controller 140 may sense a touch input of the user in the form of line 40 of one or more strokes in the first window 201 to generate a window. Referring to FIG. 3B, when the line 40 of one or more strokes is input as the touch input of the user, the controller 140 may generate a second window 203 based on the line 40. For example, the controller 140 may generate the second window 203 having a size corresponding to coordinates of an upper left end and a lower right end (or an upper right end and a lower left end) in the form of popup window. When the second window 203 in the form of popup window is generated, the controller 140 may display an application list 42 on the second window 203 as illustrated in FIG. 3C. The displayed application list may include an application icon configured by the user, an application icon which can be used in the second window and the like. In a state where the application list is displayed on the second window 203, the controller 140 may detect a touch input 44 of the user for executing an application. The user may execute a desired application through the touch input (for example, by a finger or an electronic pen) on the second window 203 displaying the application list. The controller 140 may display an application executed through a user input on the second window 203 as illustrated in FIG. 3D.

FIGS. 4A, 4B, 4C, and 4D illustrate examples of displaying a second window according to various embodiments of the present disclosure.

Referring to FIG. 4A, the controller 140 may obtain a generation request input in the first window 201. For example, the controller 140 may obtain an input (for example, generation request input) in the form of closed curve on the first window 201. For example, the controller 140 may obtain an input 50 of drawing a closed curve while pressing a button of the electronic pen 20 (for example, in a window generation mode). Further, the controller 140 may obtain a finger input of the user of drawing a closed curve in a state where the input mode has been changed to the window generation mode. Referring to FIG. 4B, the controller 140 may generate the second window 203 inscribed or circumscribed in an area corresponding to the input 50. In another embodiment, the second window 203 matching the area corresponding to the input may be generated. Referring to FIG. 4C, the controller 140 may display an application list 52 related to the second window 203 on the second window 203. The application list 52 may include an application icon configured by the user, an application icon which can be used in the second window and the like. In any embodiment, the application list may be expressed in various ways, such as an icon, a text list and the like. The controller 140 may obtain an input of selecting at least one application from the application list. Referring to FIG. 4D, the selected application may be provided to the second window 203.

According to an embodiment, the controller 140 may provide the application or a function thereof according to different attributes based on a size of the generated second window. For example, when the size of the second window 203 is a first size (for example, the size is larger than ¼ of an entire size of the touch screen 130), the controller 140 may provide the application according to a first attribute (for example, in the form of music player application). Alternatively, when the size of the second window 203 is a second size (for example, the size is equal to or smaller than ¼ of an entire size of the touch screen 130), the controller 140 may provide the application according to a second attribute (for example, in the form of music player widget).

FIGS. 5A, 5B, and 5C illustrate examples of splitting a screen and displaying a second window according to various embodiments of the present disclosure.

Referring to FIG. 5A, the controller 140 may obtain a generation request input in an area of the first window 201. For example, the controller may obtain an input of crossing at least a part (for example, the first window 201) of the touch screen 130 in a horizontal direction 62 in the window generation mode (for example, while pressing the button 21 of the electronic pen 20). The controller 140 may split the area corresponding to the first window 201 into upper and lower areas (for example, a first area and a second area) based on a position where the generation request input is obtained or the line 60 drawn by the generation request input in the area of the first window 201. The controller 140 may display the first window in at least one (for example, the first area) of the upper and lower areas and display the second window in the other area (for example, the second area).

Referring to FIG. 5B, the controller 140 may display an application list 64 related to the second window 203. The controller 140 may obtain an input of selecting at least one application from the application list 64. Referring to FIG. 5C, the selected application may be provided to the second window 203.
